DEVICE FOR ASSEMBLING OR DISASSEMBLING THE PARTS OF CENTRIFUGALLlQUlD-SEPARATORS.

SPECIFICATION forming part of Letters Patent No. 663,114, dated December4, 1900.

Application filed June 29, 1900. Serial No. 22,042. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN JOSEPH BERRI- GAN, a citizen of the UnitedStates, residing at Avon, county of Livingston, and State of New York,have invented a new and useful Improvement in Devices for Assembling orDisassembling the Parts of Centrifugal Liquid- Separators, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to that class of centrifugal liquid-separators inwhich the interior of the bowl is subdivided into a plurality of strata,both radially and vertically, by means of superposed inclined divisionrings or disks. These rings or disks may be supported in the bowl indifferent ways. For example, they may be supported upon the hollow shaftcentral of the bowl through which the liquid to be separated enters thebowl. In case the disks are supported upon the hollow shaft it may bedone by providing each of the rings or disks with a series of notches ororifices which register with radial projections from the hollow shaft.With machines using these disks or rings considerable difficulty isexperienced in removing the disks or rings to clean them. Difficulty isalso experienced in replacing the disks or rings properly in the bowl.

The object of my invention is to provide means whereby the disks can beremoved from the bowl, separated for cleaning purposes, and replaced inthe bowl with ease and despatch and without necessarily manipulating thedisks individually in the operation of removal and replacement.

The invention consists generally of a removing, retaining, and replacingdevice capable of being adjusted to the bowl and having guiding andengaging means which may be alined or registered with complementarymeans on the disks, whereby the disks in the operation of removal fromthe bowl will engage the said device and may then be slid longitudinallyalong the device independently, while being held from rotationthereupon.

More specifically, theinvention consists of a removing, retaining, andreplacing device capable of being adjusted to the bowl and havingguiding and engaging means which may be alined or registered with meanson the disks which engage one or more of the disk-supporting devices inthe bowl, and whereby the same results are accomplished. In thisconstruction the engaging and guiding means on the removing, retaining,and

replacing device will aline and register with the said disk-supportingdevice or devices in the bowl, the means on the disks whereby the disksengage the said disk-holding device or devices in the bowl performingalso the function of engaging the engaging and guiding means on theremoving, retaining, and replacing device in the process of removing thedisks from the bowl.

More narrowly considered, it consists of a construction wherein theengaging and guiding means on the removing, retaining, or replacingdevice consists of a rod or rods which are of such shape that they canreadily enter the orifices or notches in the disks, which engage thedisk holding or supporting device in the bowl. The tube or rod to whichthis rod or series of rods are connected is of such construction that itis adapted to interlock with the hollow shaft, enabling the device to bebrought to and maintained in proper position with reference to thenotches or orifices in the disks, so that the rod or rods will registerwith said notches or orifices. WVhen this position is reached, the disksor rings may be readily removed from the bowl by sliding them upon therod or rods. When so removed, any means may be adapted to lock them fromslipping off either end of the rod or series of rods. In practice therod or series of rods will be of greater extent than the vertical spaceoccupied by the disks in the bowl, and thus the disks or rings may bespread out on these rods for cleaning purposes. To replace these disksor rings in the bowl, it is only necessary to again place the device inproper position with reference to the bowl and then move the disks orrings from the rod or rods to their place in the bowl.

I will now describe the embodiments of my invention illustrated in theaccompanying drawings, in which-- Figure 1 is a side elevation of thetubular shaft, the disks or rings, and the removing and replacingdevice. Fig. 2 is a similar too View, inverted, with'the disks orrings'transferred to the removing and replacing device; Fig. 3 is a sideelevation of the removing and replacing device with the disks or ringsthereon and with its handle. Fig. 4 is a detail section on line 4 4,Fig. 1. Fig. 5 is a modified form of removing and replacing device. Fig.6 is a sectional view of same.

Ais the tubular shaft of a centrifugal liq-' uid-separator having theprojections a boy;- eled at their upper ends a.

B shows a series of inclineddisks or rings provided with the orificesI). These disks or rings are superposed one upon the other by being heldupon the projections a through the medium of orifices b.

C is the removing and replacing device,composed of the following parts:0 is a head, to which are secured the rods 0, equal in number to theorifices b in the disks, and having their low er ends beveled at 0',corresponding .to the bevel ct of the projection a.

D D are braces, to the exterior of which the rods 0 are connected and bywhich the rods, 0 are held in a fixed position relative to eachotherthat is, cannot spring in or out.

E is a rod or tube extending from the brace D. This rod E is of suchsize as to be capable of insertion and movement in the tubular shaft A.The size and position of the brace D, the position of the projections a,and their size and the distance of the rod E below the brace D are suchthat, as shown in Fig. 1, when the rod E is inserted and forced down inthe tubular shaft A the projection D will seat on the end of the shaft Aand the'ro'ds c register with the orifices 19. Under this condition theshaft A and the removing and replacing device 0 are reversed, as shownin Fig. 2, and the disks or rings pushed from the shaft A to'the device0, which may then be removed from its connection with the shaft A. Inorder to interlock the removingdevice t responding projection a.

with the shaft during the transfer of the disks or rings, I provide apin 6 in one of the rods 0, which registers with an orifice e in thecor- When the device 0 is removed from the shaft A, the disks or ringsmay be placed apart upon the device'C to enable the disks to be readilycleaned.

In order to prevent thedisks or rings passing olf either end of the rods0 and to provide a ready means to hold the device 0 during the washingof the disks or rings, I provide the following construction: Throughtherod E, the braces D and D, and the head 0 is an orifice through whichpasses the springarm f of the handle F. This armfis free at oneend,where it may be interlocked with the remainder of the handle throughthe medium of the loop f. After the device 0 has been removed from theshaft A the member fof the handle F may be inserted and looked, asdescribed, the disks or rings spaced apart, and the handle used to holdthe device to facilitate the cleaning of the disks or rings.

Instead of constructing the removing and replacing device with aplurality of rods equal in number to the orifices b, Ican use a singleguiding-rod c, which will register with one of the orifices Z). Thisguiding-rod c is projected from a hollow cylinder L, which is adapted atits lower end to surround and interlock with the shaft A.
